摘　　要：基于"亚跨超CFD软件平台"(TRIP3.0)和结构网格技术,选择SST两方程湍流模型和MUSCL型ROE格式,通过求解雷诺平均的NS方程(RANS),针对DPW4(AIAA 4th Drag Prediction Workshop)翼/身/平尾组合体构型,详细研究了网格密度、马赫数对总体气动特性和压力分布的影响。本文的计算结果与DPW4提供的计算结果的平均值取得了较好的一致。研究发现网格密度对总阻力系数有一定的影响,相比较而言对压差阻力的影响大一些;网格密度对压力分布的影响不明显。数值模拟结果与风洞试验结果的差异有待于进一步分析。Based on Navier-Stokes eq performed to compute the drag for the model is employed for the simulations of uations with multi-block struct DPW4 wing/body/tail configu turbulent flows. The effects o ural grids, CFD software TRIP3.0 is ration. SST two-equation turbulence f mesh density and Mach numbers on the aerodynamic characters and pressure distributions are carefully studied. The present numerical results are in good agreement with the arithmetic mean values provided by DPW4. It is demonstrated that mesh density have some influence on total drag, and influence on pressure drag is observed, whereas various grids have little influence on pressure distribution. The analysis of the difference between the present paper and the wind tunnel test needs additional research work.
